Recent progresses and perspectives of VN-based materials in the application of electrochemical energy storage

Developing well-behaved electrode materials is crucial for manufacturing high-performance batteries, SCs and electrocatalysis, and it is also one of the main driving forces for the development of EES devices. In consideration of the high robustness and electrical conductivity during the electrochemical reaction process, VN-based materials exhibit good performance as electrode materials (or catalytic materials) for batteries, supercapacitors, and excellent catalytic activity for electrocatalysts. Especially, the VN-based materials decorated into other active compounds with various morphologies elaborately present excellent performances due to the abundant active sites and fully synergistic effect. This review presents the structure-performance relation by designing different-dimensional nanostructures and various appli-cations of VN-based materials in electrochemical energy storage (EES) applications. Finally, the perspec-tives on future challenges and progress have been discussed. This review can offer a specific understanding for the optimization strategies of VN-based materials, thus booming the rapid develop-ment and practical applications for EES devices in the future.(c) 2022 The Korean Society of Industrial and Engineering Chemistry.
